Hello,
I'm using the uCLinux ported by Microtronix. I'm trying to use the web server but I can't see the initial page. I use the open core ethernet. I built the filesystem as described in the linux quick start guide. I can use ftp and telnet but when I type the IP in the web browser, I can't see the web page. Can someone help me? Thanks a lot, Marco19 Replies
Altera_ForumWhat direction were those packets in? If you could label every packet with its direction, that would be helpful.

Here is the summary of the Traffic. IP 192.168.1.233 is my PC and IP 192.168.1.239 is the uClinux board.

So what do you get in response if you do:
<div class='quotetop'>QUOTE </div> --- Quote Start --- telnet 192.168.1.239 80 GET /index_old.html HTTP/1.1 Host: 192.168.1.239[/b] --- Quote End --- (note the extra blank line at the end.) What does the server send back to you? - Altera_Forum
do you mean
telnet open 192.168.1.239 80 ? Then I have no response until the timeout is reached. - Altera_Forum
Can you use a unix box or telnet from cygwin under windows? I'm not familiar with the toy tools that come with windows, and I don't think that windows telnet is powerful enough to do this sort of debugging.

I have tested with telnet under linux. I created 2 testcases. Case 1 was a small website. In case 2, I added some characters to this website.

Ok, so we can see where it's failing, at least (at Boa's end, before it tries to do anything at all).
Man it would be nice to strace boa to see what it's up to. Failing that, can you cat the file on the filesystem? I mean, just make sure that any old process can read it successfully. Also, can you try creating an html file of roughly the same size as old_index.html just to try to eliminate size as an issue? - Altera_Forum
I made some tests with filetransfer over ftp yesterday.
I can transfer files with any filesize (small and large files) to the uCLinux board. but I couldn't download these files from uClinux board to the PC. I only could download files with size smaller than approximately 520bytes. That means files fitting in one ethernet packet. I think there is a problem with tx-buffering in the ethernet kernel driver. When I compile the kernel, I receive some warnings in open_eth.c. - Altera_Forum
Hello,
I solved my problem. I think the reason was the clock delay (phase) for the SDRAM. To solve the problem I changed the CPU clock in 2x Ozsillator clock (65.536MHz). The delay for the SDRAM clock is 170 degree. Now it runs on the Microtronix Cyclone 1C20 Developement board.
